TTC after abortion years ago

ella
Hi-
I'm wondering if anyone has successfully conceived after an abortion. When I was 23 I was not ready for a baby. Now that I am 30, married, and settled in my career I am trying for one, and it's not happening. I'm wondering if it has anything to do with the abortion. I get regular periods and ovulate per the OPK sticks but still nothing. I am too embarrassed and ashamed to talk to my doctor or anyone (including four my husband) about this since I have indicated I have never been pregnant.
